W refers to C. T. R. Wilson's condensation and fog limits, B to my own; T shows J. J. Thomson's results referred to scale of the diagram. Several older series, V to X, are given for dust-free air. 40. Graphs. Dust=free air.—The charts (figs. 20, 21, and 22) con- tain a number of curves showing the nucleation in different scales (com- puted from the angular diameter of coronas) in terms of the exhaustion. In figs. 20 and 21 typical cases are given, in their lower parts only. Fig. 22 contains full curves on a smaller scale. Thus the curve for the vapor nuclei of dust-free air begins appreciably below dp/p = (v1/v = i .24,.
